Filter by:The goal of this clinical trial is to learn about cognitive changes during rehabilitation in CRPS patients. The main questions it aims to answer are: - What are the cognitive changes in CRPS? - Do cognitive functions change during multimodal rehabilitation in CRPS? - What is the effect of multimodal rehabilitation on pain, functioning, mood, active range of motion, cognitive functions. Participants will undergo a 4-week program of multimodal rehabilitation of physical therapy, education and Graded Motor Imagery. Assessment will be made at baseline and after 4 weeks. Researchers will compare the interventional arm with healthy control to see if the observed psychological results are exclusive to CRPS group. There is no expanded access scheduled for this study.
This research proposal aims to investigate the potential use of Infrared (FLIR) imaging to monitor the successful achievement of the sympathetic blockade in patients with complex regional pain syndrome (CRPS).
Pain, when it becomes chronic, can be a threat to patients and it is very common to observe a fear of pain and a fear of movement (kinesiophobia). Avoidance of movement due to fear of pain can lead to a deterioration of body image. Non-medicinal therapies are essential to correct this fear and movement avoidance behavior, to decrease "catastrophic" judgments and thus anxiety. The use of art-therapy in the accompaniment of patients with pain has shown, in particular, decreases in the intensity of pain, the level of anxiety, an improvement in stress, mood and overall psychological state. However, according to the current literature, it appears that 1) this technique is rarely used in children or adolescents, for whom non-medicinal therapies are fundamental, and 2) in the case of chronic pain, the form of art used is very rarely related to the body (most often painting, drawing, music...). In this project, investigators propose to set up and test the potential benefit of art-therapy sessions related to the body, namely dance-therapy, in adolescents and young adults suffering from chronic pain.
Chronic neuropathic pain is defined as pain caused by a lesion or disease of the somatosensory nervous system. It is highly prevalent, debilitating, and challenging to treat. Current available treatments have low efficacy, high side effect burden, and are prone to misuse and dependence. Emerging evidence suggests that the transition from acute to chronic neuropathic pain is associated with reorganization of central brain circuits involved in pain processing. Repetitive transcranial magnetic stimulation (rTMS) is a promising alternative treatment that uses focused magnetic pulses to non-invasively modulate brain activity, a strategy that can potentially circumvent the adverse effects of available treatments for pain. RTMS is FDA-approved for the treatment of major depressive disorder, obsessive-compulsive disorder, and migraine, and has been shown to reduce pain scores when applied to the contralateral motor cortex (M1). However, available studies of rTMS for chronic neuropathic pain typically show variable and often short-lived benefits, and many aspects of optimal treatment remain unknown, including ideal rTMS stimulation parameters, duration of treatment, and relationship to the underlying pain etiology. Here the investigators propose to evaluate the efficacy of high frequency rTMS to M1, the region with most evidence of benefit in chronic neuropathic pain, and to use functional magnetic resonance imaging (fMRI) to identify alternative rTMS targets for participants that do not respond to stimulation at M1. The central aim is to evaluate the pain relieving efficacy of multi-session high-frequency M1 TMS for pain. In secondary exploratory analyses, the investigator propose to investigate patient characteristic that are predictive of responsive to M1 rTMS and identify viable alternative stimulation targets in non-responders to M1 rTMS.
Chronic pain is a debilitating condition affecting 1 in 5 Canadians with a yearly economic cost of over $40 billion in healthcare spending and loss of productivity. Since the prevalence of chronic pain is increasing, especially as the population ages, effective low-cost treatment is key to reduce the impact of chronic pain on patient quality of life and on healthcare costs. Due to the complexity of chronic pain and differences between the multitudes of pain conditions, developing effective treatments is challenging. This is especially true for Complex Regional Pain Syndrome (CRPS). CRPS is characterized by severe pain out of proportion to tissue trauma, with local autonomic and inflammatory changes. The severity of pain from CRPS may result in an inability to work, depression, sleep disorders, or suicidal ideation. Although its prevalence is low in Canada, CRPS is considered one the most debilitating and least understood pain conditions. As most current treatment options have low evidence of effectiveness, there is no definitive treatment available and most often, patients are struggling to maintain an acceptable quality of life. Thus, there is a pressing need to identify new and improved treatments for adults with CRPS. An early hypothesis of CRPS pathophysiology posited that sympathetic nervous system over-activity led to many of the signs and symptoms of CRPS. As such, sympathetic nerve blocks, including stellate ganglion and lumbar sympathetic blocks, have been repeatedly investigated as a potential treatment of CRPS. However, a recent meta-analysis suggests that these blocks provided no benefits for those suffering with CRPS. Newer evidence suggests that a peripheral microvascular dysfunction may underlie CRPS pathophysiology. However, no clinical trials have investigated the efficacy of a treatment targeting this peripheral pathway. The goal of this project is to assess the efficacy of a single-shot axillary approach to the brachial plexus block plus physiotherapy as a novel treatment protocol for CRPS. Our primary hypothesis is that providing a brachial plexus block in conjunction with a physiotherapy program would be superior to physiotherapy alone in treating pain and function in CRPS. Since this is a novel treatment protocol for CRPS, the purpose of our proposed study is to determine the feasibility of conducting a fully powered clinical trial.
Complex regional pain syndrome is a painful syndrome often secondary to a traumatic lesion. Treatment is difficult, of long duration with variable outcomes. Patch of capsaïcin has been proposed as adjuvant to a multimodal treatment. Capsaïcin may act by its effect on transient receptor potential vanilloid 1. Efficacity and outcome studies with this treatment are lacking. The aim of this retrospective study is to evaluate pain intensity over time assessed by visual analog scale in patient with complex regional pain syndrome treated with capsaïcin patch in addition to their usual treatment.
This work will answer two critical questions: 1) Does intensive interdisciplinary pain treatment (IIPT) involving aerobic exercise help normalize pain processing in youth with chronic pain syndromes and 2) Are aerobic fitness levels and the ability to modulate pain inter-related? Currently, medications are ineffective for improving pain and disability in youth with chronic pain syndromes and identifying non-pharmacologic treatments, such as IIPT, that help strengthen the nervous system's ability to modulate or turn pain signals down will improve outcomes and quality of life for youth suffering from chronic pain. This study will help determine whether exercise based IIPT leads to physiologic improvements in how pain is processed, specifically if youth with chronic pain can better turn pain down during the offset analgesia test after an exercise based IIPT treatment, and also help elucidate the link between a child's aerobic fitness and their ability to modulate pain.
The purpose of this study is to demonstrate safety and efficacy of a new spinal cord stimulation paddle electrode which is able to target the dorsal horns, dorsal nerve roots, and dorsal columns. The research electrode ("Study Electrode") is designed to answer basic physiological clinical research questions. It may inform future device therapy development, but the Study Electrode is not a product that will be marketed or sold. The Investigators believe the protocol is a Non-Significant Risk study answering basic physiological research questions, which may be performed under hospital IRB approval.
A 10-year follow up of a fusion of two earlier published randomized controlled trials. 203 patients with displaced distal radius fractures were randomized to surgery with a volar locking plate or external fixation.
The investigators would like to examine the role of some relevant biopsychosocial factors in the development of persistent CRPS. According to the International Classification of Functioning, Disability and Health (ICF) [43], the outcomes will belong to one of the three following components: - Body structures and functions (pain, CRPS severity score (CSS)), - Activities (disability) - Participation (return to work, quality of life). The primary aim is to assess predicting factors for chronification. The secondary aims are: - to evaluate if it is possible to classify acute complex regional pain syndrome (CRPS) patients into subgroups according to their risk of chronification. - to document the course of the disease. The main evaluation criteria will be to determine the impact of the different clinical and non-clinical variables on the course of the CRPS and on the aforementioned outcomes then, which will use as endpoints. - Primary endpoint: disability - Secondary endpoints: participation-QoL, return to work, pain, CRPS severity score.
